Question 150145
Good job, that first part is really the trickiest. Looking at all these fractions we must remember that the first three are being divided by the last three {{{((11/30)(5/6)(1/3))/((4/9)(2/3)(1/8))}}}  but instead of dividing we must multipy by the reciprocals of the last three. So we should change it to {{{(11/30)(5/6)(1/3)(9/4)(3/2)(8/1)}}} which makes simplifying do-able. {{{3/3}}} cancels out, as does {{{8/(4*2)}}}, then {{{5/30}}} turns into {{{1/6}}}. At this point I would re-write what we're now left with, {{{(11/6)(9/6)}}} or {{{(11/1)(9/36)}}} simplified to {{{11/4}}}.
